Can't see dates from Google Calender with only Busy state

[georgkrause]

I have a Google Calender, with a set of dates. These dates hide all details, its basically only exposing the start time and the end time and the event is called "busy". Sadly, non of these events are displayed and ICSx5 always tells me the calendar don't have any event.

An example event from the ICS looks like this:

BEGIN:VEVENT
DTSTART:20221104T093000Z
DTEND:20221104T100000Z
DTSTAMP:20220307T154542Z
UID:****
ATTENDEE;X-NUM-GUESTS=0:mailto:***
RECURRENCE-ID:20221104T093000Z
SUMMARY:Busy
END:VEVENT
BEGIN:VEVENT
DTSTART:20221028T093000Z
DTEND:20221028T100000Z
DTSTAMP:20220307T154542Z
UID:*******
ATTENDEE;X-NUM-GUESTS=0:mailto:***
RECURRENCE-ID:20221028T093000Z
SUMMARY:Busy
END:VEVENT

It works if I share all the information publicly.
